Kodi rheostat? Mitundu ndi Nchito

Anthu amene ogwirizana mu njira zina ndi sayansi ya, zamagetsi, wailesi, nthawi zambiri anakumana ndi mchitidwe monga rheostat a. Koma ena analibe yankho za izo. Nkhani tikambirana chiyani ndi rheostat, ndi chimene izo ziri.

Tanthauzo ndi Mitundu

Choncho, rheostat - chipangizo ongokhala resistors zingapo ndi zipangizo imene okhudza kulimbikira resistors onse m'gulu.

Mitundu dimmers zimadalira cholinga chawo:

• Pali yoyendetsa rheostats panopa, zimene kuyamba galimoto AC kapena DC.
• Ballast resistor chofunika kuyamba Motors magetsi liwiro ndi panopa zonse ndi lamulo ake.
• The ballast kapena katundu resistor - magetsi zida chifukwa mayamwidwe mphamvu pa lamulo Napempha kwa jenereta kapena pa katundu anayendera jenereta.
• Rheostat malemeredwe chofunika kuti zonse ziliri pa windings kukhala AC makina magetsi kapena panopa mwachindunji.

Zofunika ndi Wozizilitsa

Chimodzi mwa zinthu zazikulu zimene kudziwa zinthu mamangidwe chuma chimene chikuphatikiza rheostat. Ndipo chifukwa cha zimenezi zikhoza kugawidwa dimmers pa ceramic, madzi, zitsulo ndi malasha. Magetsi resistors ndi n'kukhala kutentha, zimene ziyenera zichokera kwa iwo. Choncho, rheostat ndi mpweya ndi madzi kuzirala. Mtundu lachiwiri madzi kapena mafuta. Air mtundu ntchito iliyonse rheostat yomanga. The madzi okha zitsulo, chifukwa resistors zawo streamlined madzi kapena kwathunthu kumizidwa mu izo. M'pofunika Pankhaniyi kudziwa kuti madzimadzi ntchito kuzirala, komanso yokha ayenera utakhazikika kapena mpweya, kapena madzi.

rheostats zitsulo

ndi rheostat zitsulo chiyani? Ndi mchitidwe wokhala mtundu mpweya kuzirala. rheostats amenewa ambiri, chifukwa mosavuta kusinthidwa kuti zosiyanasiyana zinthu opaleshoni. Zimenezi zikukhudza makhalidwe onse matenthedwe ndi magetsi, ndi magawo kapangidwe. Iwo akhoza kukhala ndi analowa kapena mosalekeza mtundu wa kusintha kukana.

Siwichi ndi lathyathyathya. Iwo ali kukhudzana makina kuti zithunzi pa kulankhula ndi yoikidwiratu mu ndege yomweyo. Anthu ojambula kuti Usaigwedezere, wopangidwa mwa mawonekedwe a zomangira ndi lathyathyathya mitu cylindrical kapena hemispherical mtundu mwa mawonekedwe a mbale kapena matayala, amene oyenerera mu Arc mu mzere umodzi kapena iwiri. Kukhudzana zokwawa amatchedwa burashi. Iwo akhoza kulithetsa ndi chokhethemulira kapena mtundu wake kukhazikitsa.

Koma pali kusiyana mu kudziletsa aligning ndi nesamoustanavlivayuschiysya. Njira yomaliza kapangidwe kosavuta, koma, monga zambiri kukhudzana wasweka, si abwino ntchito. Kudziona aligning kukhudzana avundulidwe amatipatsa digiri kofunika kukanikiza ndi ntchito yodalirika kwambiri. N'chifukwa chake mtundu uwu ndi ambiri.

Ubwino ndi kuipa kwa masiwichi lathyathyathya

Ubwino wa masiwichi lathyathyathya-mtundu monga kapangidwe yosavuta, kukula yaing'ono ndi nambala yaikulu ya masitepe, mtengo wotsika, yolandirana, disconnecting ndi kuteteza kulamulira dera la.

Pakati pa zovuta pang'ono taonera osakwanira kusinthitsa mphamvu, ang'ono kusinthitsa mphamvu. Ndipo chifukwa cha mikangano ndi kusungunuka pansi msanga amapita burashi.

mafuta kuzirala

Zitsulo rheostats mafuta-yozizira mtundu kutentha mphamvu ndi chinawonjezeka ndi Kutentha nthawi chifukwa cha zabwino kutentha madutsidwe mafuta. Izi zimathandiza kuwonjezera katundu ntchito zing'onozing'ono kuchepetsa mowa zakuthupi ndi kukula kwa resistors rheostat.

Zinthu zimene amizidwa mu mafuta, ayenera kukhala pamwamba lalikulu kuonetsetsa zabwino kutentha kutengerapo. Ngati chatsekedwa-mtundu resistor, izo zimapangitsa neza kuviika mu mafuta. Nkosafuna kumiza amapereka ojambula chitetezo ndi resistors chifukwa cha zinthu zachilengedwe. The ojambula mafuta tripping kuchuluka mphamvu. mwayi uwu wa dimmers mtundu uwu. Chifukwa kondomu mwinanso kukanikiza pa kukhudzana ndi. Koma pali zovuta. Izi kuwonjezeka chiopsezo zowopseza moto ndi kuipitsidwa kwa malo a.

rheostat mwina mbali dera monga resistor variable kapena potentiometer. Izi zimabweretsa kusintha yosalala kukana ndipo, chotero, lamulo la mphamvu panopa ndi voteji mu dera la. Mankhwalawa amagwiritsidwa ntchito mu Laboratories.

ballasts rheostats

Rheostat ndi kusintha sitepe mu kukana, zopangidwa resistors ndi chipangizo kusintha wopangidwa, nayenso, kwa anzanu ndi yoikidwiratu, kukhudzana kutsetsereka. Apa pali pagalimoto.

Yambani ulamuliro dimmers ndi mitengo yonyamulira ya armature, chimene chikugwirizana ndi kulankhula ndi yoikidwiratu. Kukhudzana makina atseka ndipo anatsekula mlingo kukana, komanso madera ena omwe ankalamulira malinga rheostat a. Actuator rheostat mwina galimoto kapena pamanja. Yotani? Rheostat mtundu imeneyi inafalitsidwa. Koma kuipa mamangidwe ulipo. Izi ambiri mawaya khamu ndi mbali kwa kukonza. Makamaka zambiri iwo rheostat malemeredwe ndi ambiri masitepe.

Rheostat wodzazidwa ndi mafuta lopangidwa ndi chipangizo kusinthitsa ndi mapaketi resistor amene ophatikizidwa mu thanki ndi kumizidwa mu mafuta. Mapaketi zigwirizana zinthu zopangidwa ndi zitsulo magetsi. Iwo amagwira ku thanki chivindikiro.

The chipangizo kusinthitsa ali ndi maganizo a olamulira ng'oma ndipo Ufumuyo thereto ndi cylindrical mbali pamwamba omwe ogwirizana malinga chiwembu cha. ojambula mapulani amene olumikizidwa kwa nyengo resistor ali wokwera pa njanji lokhazikika. Pamene ng'oma olamulira imazungulira pa galimoto kapena flywheel, anthu ena a Kuthana atathana ojambula, ndi kulankhula makina kukhala. Kumasintha kulimbikira mu dera la.

Pamwamba kwathunthu kulongosola funso, kodi rheostat. Monga mukuonera, ichi ndi chinthu chofunika kwambiri, chimene chimagwiritsidwa ntchito zosiyanasiyana m'madera magetsi.
